It's not clear to me how this change solves the issue. It's a "read
timeout" so this means the connection has been established. The client
will not care if the server has enabled SO_REUSEADDR or whether it
initially bound to a fixed or ephemeral port.
Is this issue Solaris only? I ask because there is an awkward issue on
Solaris where the kernel will accept a pending connection when the
process is at its file descriptor limit. We've seen this periodically,
esp. with tests that leave connections or files open. An unsuspecting
tests runs later, establishes a connection but gets timeouts as there
isn't no code at the application level has accepted the connection.
